Absolutely not.If we were doing the "work of God" we'd see ourselves in a proper light on a daily basis yes?
"Nor should there be problem with Peters admonition that we be eager to make our calling and election sure. 2 Peter 1:10"
I'm not sure that 2Peter 1:10 means what you seem to think it means.
If you had a choice between doing what had been asked by Jesus and not doing it, then surely you would say that you’d rather be doing it than not doing it.
And, if as one who was doing what the Lord asked, would that not give you greater assurance than if you were not doing what had been asked.
As Jesus said, “Happy is the man who does these things.”
